Japan seeks foreign engines for stealth fighter prototypes

Japan is looking to use foreign engines for the prototype aircraft needed for its fifth-generation fighter programme.

The ATD-X Shinshin programme is still in the study stage, but industry sources in Japan and overseas say Tokyo has issued a document to engine-makers seeking information and pricing on powerplants needed for two prototype aircraft.

Japan had wanted to buy Lockheed Martin's F-22 to meet its future fighter requirement, but the US government has barred exports of the type and agreed to halt production for the US Air Force. Tokyo has responded by vowing to develop its own fifth-generation fighter under the ATD-X programme.

Local engine-maker Ishikawajima-Harima Heavy Industries (IHI) has been assigned to develop the XF5-1 engine for the ATD-X. The move to source foreign engines for the prototypes could be part of efforts to give IHI more time and ensure that the overall programme remains on track.
